Vertical roller mill manufacturer

One of the most popular types of vertical roller mills is the ball mill. Ball mills are very versatile and can be used for a variety of applications. For example, they can be used for grinding, mixing, and blending materials like cement, coal, or limestone. Ball mills are also very efficient at producing a high quality product.

Another type of vertical roller mill is the rod mill. Rod mills are less versatile than ball mills but are still very effective at certain tasks. For example, they excel at grinding and mixing materials like ores and other minerals. Rod mills are also often used to pre-grind materials before they are sent to a ball mill.

The last type of vertical roller mill we will discuss is the tower mill. Tower mills are similar to ball mills in that they use Grinding media but instead of using balls they use rollers that rotate around a central axis. These rollers grind the material as it passes through them much like how a traditional flour mill works.

The advantages of Vertical Roller Mills

The advantages of Vertical Roller Mills are numerous. Some of the most notable benefits include:

- Increased Efficiency: Vertical Roller Mills are up to 30% more efficient than traditional ball mills, meaning they use less energy to grind materials. This results in considerable cost savings for businesses who rely on VRMs for their grinding needs.

- Improved Quality: The rolling and grinding process used in VRM result in a more uniform grind, which leads to improved quality products. Additionally, the pressure exerted by the VRM on the materials being ground can lead to improved durability and strength of the finished product.

- Reduced Maintenance Costs: VRMs typically require less maintenance than traditional ball mills, due to their simple design and lack of moving parts. This can lead to significant cost savings over time for businesses that utilize VRMs for their grinding needs.

How does vertical roller mill work?

The working principle of vertical roller mill is based on two to four grinding rolls with shaft carried on Hinged arms and riding on horizontal grinding table. The ground material is supplied onto a rotating grinding table connected to a bevel-spur gearbox, driven by electric motor and hot gas flowing through the nozzle ring. The raw material is ground by compression, shear and friction between the rollers and the rotating table.

The main advantage of this system is that it can cope with variable raw material quality. The mill is suitable for both dry and wet grinding of various kinds of materials, including cement, Portland cement, limestone, kaolin, bentonite, iron ore, coal etc.

Applications of vertical roller mill

The vertical roller mill has a wide range of applications in the fields of cement, power, chemical and metallurgy. The vertical roller mill is a kind of crushing equipment that saves energy and is highly efficient. It is suitable for crushing materials with Mohs hardness below 9 and humidity below 6%.

The vertical roller mill is widely used in the following industries:

1. Cement industry: The material is ground by applying pressure to it between two rollers (the so-called "grinding table"). The material passes through the table until it reaches the desired particle size. The material then falls down into the space between the rollers and is transported out of the mill by gravity or by means of air flow. The finished product is collected in a bag or dust collector.

2. Power industry: Coal and limestone are ground to a fine powder in a horizontal roller mill and delivered to the power plant furnace for combustion.

3. Chemical industry: Various chemicals are ground to a fine powder in a horizontal roller mill and used as catalysts, pigments or other additives in various processes.

4. Metallurgy: Various metals can be ground to a fine powder in a horizontal roller mill and used as raw material for powder metallurgy or other processes.
